[sdiy] Oscilloscope Probes

[Scott Gravenhorst]

Hi Peng,

3 probes won't ever hurt and might need 3 once in awhile.  Imagine wanting to display 2 different
signals while triggering off of a third.  On mine, BK model 2120, I have 2 verticle inputs and a
trigger input, all BNC connectors, so you can do what I described.  If you can afford them, I'd get
them.  

I'm not sure on the MHz issue, I'd guess what you said is true.
